David Nebenzahl - 16 Oct 2004 20:33 GMT
Leaving aside any of the philosophical and semantic aspects of his argument,
there's one glaring error in his argument. He asserts that because digital
formats change (true) that digital images made now will become unreadable in
the future.

Now, if one is discussing images made on physical media (film), there *is* the
distinct possibility that the image will be rendered unusable through time
because of physical degradation of the image. (Witness movies on nitrate stock
and color negatives or slides with unstable dyes.)

And in the case of digital media, there is always the possibility that the
image will become unreadable because of *physical* degradation of the media
(tape, magnetic disc, optical disc, etc.)

However, assuming that the *physical media* remains intact, it is very, very
unlikely that any digitally-recorded image will ever become unreadable in the
future.

I do know something about this, having worked for a computer media conversion
and duplication company for 13 years. In that one small company alone, there
exists the ability to read many obsolete digital formats (meaning both the
equuipment and the software to decipher the data and deliver it in a usable
form): specifically, 9-track tape (remember the old movies with the computers
with the spinning tape drives?) and floppy disks, including the old 8" monsters.

I'm confident that even data on paper tape could be read; someone, somewhere,
has a paper-tape reader connected to his S-100 system (running CP/M), or some
other moldy oldie. And if not, a reader could pretty easily be cobbled together.

The point is that humanity doesn't collectively forget its own obsolete
recording formats, just because something new comes along. Sure, the old
formats fall into disuse and become difficult to use, but not impossible.

Why, in this very house, I can right now play 78 rpm records if I like, or 45s
 even. I can also read all of my old 5-1/4" floppies on my computer.

I'd like someone to try to name a data storage format (either physical medium
or data format) that they think cannot be read today.

 The oldest media you are dealing with is probably the 9
track data recordings. How old are they? probably not more
than about forty years, if that. In order to read them you
need to have the transport, heads that match the format, and
know what the format is. This is quite different from
"reading" still photographs, which requires no equipment
other than the eye, even for negatives. Motion pictures are
more difficult if one requires reproducing the motion but
the subject matter is also visiblel to the eye with no help
(other than perhaps a magnifyer). Also viewer and projector
technology has not changed fundamentally in over a century
and is still used.
  More difficult will be the recovery of data from formats
as common as floppy discs. It will probably be possible but
will require the construction of suitable reproducers. While
a floppy drive is very cheap now it won't be when they are
no longer made and must be constructed as a single specialty
item.
  The fact is that recovery of archived material on
photographic film requires little specialized equipment
while digital data will always require a lot of specialized
equipment.
  It is difficult to predict the future of technology.
Usually, predictions are based on extrapolating from current
technology but there is no way to predict a "break through"
based on new scientific discovery. Science and technology
are different in a very fundamental way: science is the
discovery of natural laws or principles; technology is the
application of known laws or principles. It is also possible
that computer technology will eventually reach some sort of
equilibrium. It is still a new art (IMHO) which means it is
changeing rapidly, but that rate of change may itself change
in the future. Here again is an unpredictible factor because
we don't know what discoveries may be made which may
accelerate change.
 Certainly digital archiving will become more reliable in
the future because it has to in order to be useful.
 Other forms of electronic storage than digital have also
suffered from rapid change in technology. When I started in
the TV business 2 inch segmented scan video tape recorders
were common. Now they are found only in specialty dub houses
for the purpose of recovering material recorded on that
format. The example of a 78 disc is trivial. Cylinder
recordings are perhaps a more apt example of old technology
which yields recoverable data but cylinder recordings were
never used for long and are comparitively few against disc
recordings.
  Now, having said all this basically I disagree with the
original premise that electonic images are not photography.
They obviously are despite any argument about longevity.

Everything you say is so; my point was simply that it will undoubtedly be
possible to read digital images, even from obsolete media and formats, in the
future. You pointed out that it may be difficult to do so, which is true. But
it will still be possile.

Sure but if it's going to cost hundreds of bucks per image to recover them,
how many will be recovered?

BTW I have some paper tapes from a 1970's wang machine, know someone who can
read them for the same cost as looking at the photo's I took at the same
time?  :-)

Welcome to the killfile david...
Bob Monaghan - 17 Oct 2004 23:53 GMT
NASA, with multi-million dollar budgets, couldn't recover much of the data
they had stored on tape from the early space probes (Ranger..). So a bunch
of rocket scientists, with all the $$ and support engineers and software
geeks in NASA, can't recover their own digital tapes 30 years on, right?!
Doesn't say much for our odds for recovery 50 or 100 years from now? ;-)

The first reason most digital images are going to be lost is that most
such images are not recorded on permanent storage media in the first
place. By most, I mean 63%, as found in a digital camera user survey by
Fuji-UK (see BJP PROFESSIONAL NEWS - 21 May 2003 for details), where most
users had images stored on their computer hard drives -with no backups!

Second, most of the remaining images are not going to be properly managed,
meaning they won't be recopied every year or two, or converted to new
formats etc. Like most photographs of the past, those CDRs are going to
end up in a shoebox in a hot attic, and chemical "bit-rot" will make them
unreadable in a decade or less. Magnetic "bit-rot" kills off that form of
storage media quickly too. These losses can be catastrophic in many image
formats using compression, where most of the image is encoded as offsets
from an initial value. Even worse are images with encrypted or protected
or enbedded features. We already have "data archeologists" (seriously) who
specialize in excavating data from older corporate databases and resources

Third, for the few % of images that are recorded on "archival media",
failure to strictly maintain temperature and especially non-exposure to UV
will mean far shorter lives than claimed in the ads. And you may have
noticed that a number of so-called "archival" CD products (e.g., Kodak..)
have been withdrawn or recharacterized for longevity, yes? ;-) This is a
really big deal for digital librarians and others in the data storage biz.
Film remains the only proven archival image storage media today...

Fourth, the number of proprietary formats continues to explode in number
(e.g., raw data), with lots of "streaming" updates in software upgrades
added to products. The number of incompatible file compression formats is
also quite large. The number of operating system variables are large (cf.
XP vs. MS-DOS etc. ;-). And lots of those software programs have bugs and
"features" which may prove critical to recovering or reconstructing the
original data decades from now. So, how many of us have recorded all this
information with our CDs, so we could reconstruct the creation environment
say fifty years from now? None, right? ;-)

Fifth, your experience as a data conversion company worker is different
from mine. I "inherited" a nifty heathkit version of a DEC minicomputer,
complete with software and 8" diskettes etc. The original owner had spent
years searching online and with our campus archivists and librarians for a
service that could convert her original dissertation notes and resources
off the 8" diskettes in some odd freeware word processor format to
MS-WORD. Nobody could do it. Not even the heath user group folks could
help her out That was less than 20 years old hardware and software too,
rather less than 100 years, eh? ;-)

What does Fuji-UK recommend?  They suggest that if you have something you
really want to be sure is available archivally decades from now, you
should get it on FILM (!) :-0) Makes sense, since film is a direct access
medium (no computer hardware or software required) with proven archival
potentials (with proper fixing etc.). And the US government continues to
mandate COM (microfilm) as their archival medium of choice etc.

The sad part here is that the very vast majority of digital images being
made by regular people will be lost, not in a century, but at the next
hard drive failure or virus attack (63%..), most "archived" CDROM images
will deteriorate from chemical "bit-rot" in the next decade or so etc.

Just as parents are upset to discover that their VHS tapes of their kids
can't be viewed at the kid's graduation from High School, so to are most
of today's digital users likely to be disappointed that their digital
images are lost over the same double decade time period.

In the meantime, lots of us will be glad we were shooting on film in the
first place ;-)

I don't even work in the computer industry but have witnessed this first
hand at least a dozen times. People store their digital images on the same
partition as their windows install! They pop in the restore disk that came
with their computer and are shocked all their childen's pictures are gone.
And of course they never printed any of them so they are GONE.

Of course with enough diligence this can be avoided but how many people are
going to take on the active -fight- of keeping all their images safe? I'd
bet less than 5% of digital camera users will.

Some good points, bob, but what in particular
do they have to do with MF photography or the
original topic of this thread?

Agreed, lots of folks now shooting digicams
will be in for a rude surprise somewhere down
the line.  They will either learn from that
experience.. or not.  By definition most of
those who lose data will be casual users.

In the meantime, I feel I'm pretty well
covered - shooting mostly with film and
printing digitally.

On images captured digitally, I need to be
super vigilant.  Yes, I've already lost a few
images.  I'm not looking backwards -- just
can't see any point in doing that.

Yes, it's good to be reminded of the
volatility of digital data.  Even so, I'm
sure the storage technologies will continue
to improve rapidly.  Four years ago a 100 MB
Zip disk was the standard, at $10 a pop.  
In 2004 it's a DVD, with 47 times more
storage at 1/10 the cost.

Can you cite evidence that present CDs
and DVDs are subject to magnetic "bit rot?"
I believe you are mistaken on that point.

True, just as so many families had a rude surprise when they saw their color
photographs from the '70s and earlier fading and discoloring beyond
recognition ("and why oh why didn't we keep all those negatives somewhere so
that we could find them today?").

The Heath UG may not have been the place to look.

IIRC the Heath was based on the PDP-11 single-chip CPU.

Did she try the various PDP-11 groups?  There will (should) be
a great deal more expertise there than in the Heath group.

http://www.hampage.hu/pdp-11/

It seems the '11 is still made and used in Ireland and Hungary.

However, the magnetic coating on those 8" disks may have turned to goo.

Polyurethane - the stuff used for camera light seals - is the binder
used in magnetic tape and floppy discs.  And we all know long-lasting
polyurethane is, right?

"Odd freeware" and PDP/11 don't go together. ;)  But the real question is
How much is the person willing to pay for a conversion, and will plain text
do? The VAX 11/780 and a few others still had the option to boot from 8"
discs, and there is a fellow in Wisconsin with a few DEC VAXen and PDP's
under RSTS/E, RT-11 and RSX. So, how much? A couple grand okay?

Surprisingly enough, I think they do.  For college kids in
the late 60's early 70's this used to be their 'personal'
computer (as in being in the computer center from 2am to 6am)
- so you can imagine what got written for it.  It soon
became the hobby system in the 70's. I had several friends
with 11's made from 'surplus' parts bought at hamfests
(Prof: Hey!  What happened to my computer?  Where'd the
front panel go?).

> How much is the person willing to pay for a conversion,

You would need to find an 11 user with a copy of said WP program
and 8" drives.  Such may not exist.  The logical place for this
rig, an HT-11 UG did come up empty according to the OP.  There
were way more PDP-11s than HT-11s, and if the disk drives and
software were the same as used on the HT-11, then there may be
success.

My guess the cost is zilch.  Or if you go to someone who makes
a living at it, well who knows ...

If the data can be moved to PC format it may be possible to
pull the text out of the files with a binary editor.

Now, what sort of 8" floppy: Single sided; Double sided;
Hard sectored; Soft sectored; Number of sectors; Tracks per
inch ...?

I don't even want to think about having to deal with 8" floppies!! I had
some fun about 5 years ago when I retired an old Sun server because it wasn't
capable of running a y2k compliant OS. I shut it down and scrapped the server
but hung onto the SMD drives. Two monthes later I got a call from a user that
demanded that I reconnect the SMD drive to another server so she could recover
data from it.

As those of us in the IT field know and have been upfront about is media
obsolecense<SP?> is an issue. Another problem is what to do with data that you
can read from the media but don't have the software to deal with the data. This
is of course a bigger issue then just what to do with digital images.

I was suggesting that it was unlikely that it was freeware if it was used by
a faculty member for her dissertation. Could be, but more likely it was
DEC's first word processor, the DECMate (PDP/8, a 12-bit OS).  I know that a
lot of student-ware was written for the PDP/11, and for the time period you
mention, it was likely written in DEC BASIC. Omsi Pascal didn't come out
until about '77 and it was still buggy. Their only other alternative was
lower-level languages, and not many made good lower-level programs. Can you
tell I was there?

I said there's a DEC VAX 11/780 (maybe 11/785) out there. With the exchange
program (which read/writes PDP/11 formats) it can be done.

The person I'm speaking of won't do squat for squat because it takes more
electricity to run those machines that it's worth and the demand for
programmers for obsolete hardware is about gone.

Not an issue. Open the media as a non-file structured device and go for it.
We had _lots_ of tools to discover formats.

You can't open a hard sectored disk in a soft sector drive, and visa
versa - remember the disks with the ring of index holes?

They obviously are not, Richard, since

1. the process are different and produce different results.

2. Digital silicon sensors do not and cannot produce a
photograph. What they do produce is a voltage based on the
photoelectric effect. This is then regenerated into digital
signals that are then used to output reproductions of those
signals. At no time during this process is there an optical
image nor any photograph. A photograph is an image produce by
the direct action of light. Digital does not do this nor can
it. The physics don't allow it.

3. The ISO standard states definitively digital still cameras
produce a signal that _represents_ still pictures, not actual
pictures.

As I've pointed out in my posts in rec.photo.darkroom (now
being cross posted and the discussion deliberately taken out
of context...), people need to look at the processes to
determine what digital is vs. what photography is. Looking
at the end result is misleading, since in our society the
words photo and photographic have come to idiomatically mean
any image we see. But as we all well know calendars, though
we call them photos/photographs, are not. They are offset
reproductions. Simialrly paintings are pictures, but they are
not photographs. Digital produces pictures and reproductions,
but there is no original photograph created by digital imaging.

  What is the definition of Photography?  I think that
fixing it as a method of producing pictures via a particular
chemical process is not sufficiently broad. Is television
photographic, it is completely electronic (I am excepting
the use of motion pictures are original material, they are
transmitted by electronic means). I think this argument
confuses the method with the result. Digital photographs are
"pictures" as much as chemical ones are once they get to the
finished form.
  If silicon or any other elecronic sensors (they are not
digital) do not produce pictures what do they produce?  If
you say an electronic signal you are partially right, that
_is_ what comes out of the sensor, but it is not the
_result_ of what comes from the sensor. The _result_ IS a
picture.
  Also, "electronic" is not interchangibe with "digital".
ALL of the electronic signals used for digital  imaging
purposes represent analogue functions. Even those which
start out in life in the digital domain, such as the output
of graphics generators, are meant to be translatable to
analogue form in order to be meaningful to the human
sensorium. Digital referes to a method of encoding analogue
information in order to store or transmit it. In some ways
digitally incoded information is superior to the original
analogue information for transmission or storage (and in
some ways is not). This has nothing to do with the process a
user goes through. A person using an electronic camera to
produce images which are to be reproduced on a computer
screen or printed on a computer printer, can be a
photgrapher just as much as someone using chemical methods.
It is the production of the image that defines the process
not the means.

Pictures yes. Photographs no. Digital is a different medium,
and if a different medium it cannot be the same medium, i.e.,
photographic. Painting is likewise an imaging medium and
produces pictures. But it is not phototgraphic. The _process_
is what defines it, not the result. And if the result also
defines it, then digital is still not photographic, since the
results are very different. Pictures are not photographs, a
silver images created by the direct action of light is a
photograph. Digital simply doesn't do this. It creates data,
which is then use to image a "picture" by any various methods
of output. This is where most people are confused IMHO.

The result is a signal that is regenerated into data. That's
what they produce. The "picture" part is a reproduction of
that data. This is what digital does. It is not what
photography does. It is not a photographic process, it is
digital imaging process. If you wanted, you could output
that data in other analytical forms, or as 1's and 0's.

This is why we call digital "digital imaging," rather than
the term _phos graphos_ which was intentionally applied to
a light actuated chemical process by the eminent scientists
of the day

But they don't represent photographic functions, since
no image actually exists. The ISO states digital images
are representational images until output. And they
are correct.

Well I'm not sure what original analogue info you refer to.
As regards digital cameras, which image by the use of
photodetectors, I disagree. All digital cameras are
limited by Nyquist, and cannot be superior in any way
to the original analogue (scene) information. Signal
frequencies must be reduced due to nyquist and there
is no way around this. This is why digital images for
pictorial purposes can never equal the resolution abilities
of silver halides, which for all practical purposes mirror
the original analogue information.

BUt there is no image in the digital process. When the
data is output, there is an image, but it is not a
photographically produced image.

I made my original post to rec.photo.darkroom. This
deliberately crossposted discussion is therefore out

Oh, come on, give it up; admit that all you're doing is engaging in semantic
hair-splitting.

OK, you assert that a CCD doesn't produce a picture, but only a
signal--voltage levels corresponding to illumination values at each pixel.
Fine. Then I say that photographic film doesn't produce a picture either, just
altered electrical charges in silver halide atoms.

You can't see a picture on a CCD, true. Neither can you see a picture on an
exposed piece of film (or paper). Just as the CCD signal requires processing
in order to render it into a photograph, the film requires processing.

You have no case. Next!

All I'm saying is, to people who are out there seriously making images with

It was crossposted minus the original thread/posts. Deliberately.
As in deliberately out of context.

That's Trolling with a capital T. Your grasp of what it means to
troll seems as poor as your grasp of what a photograph is and is
not. A photograph is not merely anything you hang on the wall (a
very shallow and superficial defintion.) If that were true, my
Sierra Club calendar of images would also be equal to a collection
of photographs. They're not. They're offset reproductions.

The _process_ determines what a photograph is and isn't, not
the resulting "picture." Digital is not a photographic process.
It's an electronic data imaging process that in scienitific reality
produces no optical image. Ever.

Only the photochemical process actually writes an image with light.
Digital does not write with light, it transmits a photoelectric
signal and no image is produced. Period. Digital images are
rather reproduced output (like the calendar) from digital signals,
not from light.

I just don't know why this is seems such an abstract a concept
to people. One produces an image; the other creates a file. Not
really complicated or abstract.

As regards the terminology (i.e., use of the terms photograph/
photographic) we are talking about a scientific application of
a scientific term for a scientific process, which photographgy
is -- not the evolving common English vernacular. As an professed
English MA, you should well know the difference. Examine the
process, not the idiomatic usage.

It's funny how you seem to be insulted by any opinion contrary to your own.
At any rate, I made no claims one way or the other as to what constitutes a
photograph, ergo your claim that my "grasp of what it means to troll seems
as poor as your grasp of what a photograph is and is not" is little more
than an ad hominem insult.  You're good at those, too bad your ability to
put your emotions aside and _really_ look at what a person is saying is less
developed.

As for my comment on degrees, you said, and I quote, " English was my major
(along with photography) in college" (as though that proves something
concerning your ability to discern semantic nuance--it does not, and is a
very poor argument on your part).  So, yeah, I guess you're right, you could
have an English major without a degree.  But then that's playing at
semantics again--story of your life, apparently.

Finally, you're the only one I see disrupting the group with your angry
arguments, so I guess that makes you the troll, yes?  Yes.

I won't waste my time with your tantrums any longer.

For an English MA you don't read a thread very well, do you?
_I_ didn't post this thread. But the thread has _my_ name in
the subject. Now, wonder why that is? ANSWER: a troll took
it from another nsg and posted it here. IT'S CALLED FLAMING.
GET IT??? Know what trolling and flaming are?

If not you need to go back to USENET school. 101.

BTW, you said, and I quote: "Your [my] argument is absolutely
meaningless to any photographer living or dead. And I have a
masters in English, so that trumps your "major"."

Well, now, I was merely stating I had a background in English,
i.e., I understand both semantics and photography. Gee, shoot me.

But like the troll you merely make unfounded assertions and ad
hominems (appeals to personal considerations rather than sound
argument.) In others words _you_ began this exchange, and attack.
I have at least made posts based on logical argumentation for
the most part. Of course most of those posts relating to this
misappropriated thead are in _another_ nsg (get it?), where
the referenced subject actually is.

Your argument is (1) a fallacy, since you cannot possibly speak
for "any photographer living or dead." (2) An appeal to your own
superiority (also a fallacy) which was in fact an intended as
an insult. (3) I am a photographer (sorry, but that means a
schooled photographer who knows more than just what _your_
point and shoot digital camera manual tells you...) and I
know many other photographers (probably more than you do) and
none consider this issue "meaningless."

It seems to me that this thread has become muddied. I hope you don't mind if
I try to clarify some points. Let us begin with one clear statement.

It seems that Tom. Phillips is trying to make a distinction between 1) the
making of source images made by 2) conventional film and 3) images made by
light-sensitive digital sensors. Is that correct?

1-3:

1) making of source image - the capturing of the first version of an image,
and NOT the copying or creation of an image from another image, regardless
of its kind. In other words, even making a copy of a conventional film
photograph of an original film photograph is not "photography" per se. What
we are trying to distinguish here is the nature of the creation: light
falling upon a three-dimentional surface and not a derrivation from such.

2) conventional film - the silver-based emulsion that we know to be derrived
from that used since classic glass plates, flexible films today, or painted
onto any surface and NOT a film yet to be invented or not yet in popular use

3) light-sensitive digital sensors of any kind

IS THIS CORRECT SO FAR?

We can explore the nuances that distinguish Tom's definition/view after we
settle the above.

> 1) making of source image

I would put it as:

  "The capture of an image of the original subject by the action
   of light."

I would allow a print as the 'photograph of a photograph' as it fits the
definition and minimizes endless nit picking.

> 2) conventional film - the silver-based emulsion that we know to be derrived
> from that used since classic glass plates, flexible films today, or painted
> onto any surface and NOT a film yet to be invented or not yet in popular use

My interpretation:

 "A film (bad word, could be a cyanotype, etc.) image is a physical
  medium that forms a 'permanent' image due to the direct action
  of light from the subject."

> 3) light-sensitive digital sensors of any kind

I would differentiate digital from film (for lack of
better words):

 "A digital image is pure abstract data representing the
  action of light on the subject."

There is nothing to say that a digital image has to exist on a
physical medium:  it can represented by a cloud of electronic charge,
a current, or as the memory of a string of numbers, among many others.  
And there is nothing requiring the image to be quantized - it can
be an analog value, though at the limit everything is quantized.  The
action of the subject's light on the viewable image is not direct.

We need new terms:

"Physical imaging" (film) Vs "Ephemeral imaging" (digital)?
- I know, awful choices -

But they are both 'photography' in my book.  Outside of fetishists,
the person hanging the image on the wall couldn't give a rat's a.s about
which it is.

With this I disagree. Anyone buying images as art most
definitely gives a rat's a.s. This is why no gallery would
sell an inkjet as a "photograph," but as a digital image.
Similarly, photographs are labeled according to what they
are (i.e., the _process_): silver gelatin, cyanotype,
chromogemic, etc.

These are not semantical differences, as David the troller
insists. They are legitimate distinctions of the various
processes employed. Digital imaging is digital imaging.
The term "photography" has been abducted (conveniently)
in order to market digital as "digital film." Of course
it is not film in any sense or function nor does it
produce a photograph.

If a scanned copy, it is digital imaging. If a photochemical copy,
it is a copy negative. Even photochemical terms makes specific
distinction depending on the processes employed and always have.

What I'm trying to do is pin down the original author's internal view, his
ground of what he considers photography, for example is it strictly light
falling upon a traditional recording medium and intended to make a "picture"
(rather than the phenonema of sunburn or something like that)? Or is it
anything other than digital?

I suspect the author is fostering a romantic notion of photography vs. this
new digital stuff - the superiority of "that which came first" kind of
thing, without speaking to what makes it superior.

By and large, we no longer communicate via
chiseling symbols into stone.

In our age, the permanance of a photo will
be determined by its universal appeal --
this will determine whether adequate efforts
will be made to preserve the image over the
ages.

Ie. permanence is an attribute of the
"post processing" and not necessarily
an attribute of the message or image
at the instant of its creation.

Permanence is of course relative.

Unprocessed film images can remain latent
for years, even decades -- but I'd still
not refer to them as permanent.

I have a degree in philosophy and have published in Semiotica, and I
say the MEDIUM makes no difference whatsoever in calling something
'photography'. The FUNCTIONAL meaning is what's important, and since
the image derives mechanically from captured focused light rays, it's
photography.

I should add was applied intentionally to describe
the photochemical process, i.e., the direct action of
light in a chemically actuated process.

The idiomatic use of the words "photo" and "photography"
in our society do not negate this intentional, original
application. Television cameramen are called "photographers"
rather than videographers. Movie makers are called photographers
rather than the more proper cinematographers. The term
photography and photographer is so diluted as to have
become meaninless in our society.

So are you one of those people who insist on calling tomatoes and peppers
"fruit"? Because technically they are. (The seeds of a plant and that which
contains them.) It's just that 99.95% of people misuse the term and insist on
calling them vegetables.

This is just as relevant as your insistence on the narrowest usage of
"photography". You may even be technically correct--who knows? (Or cares?)

If you really want to pursue this, I'd suggest going on over to

Photography to me is capturing a moment in time. You can define it in a
narrow way so that only your way of doing it is photography. IMHO if what
you display never actually existed in front of the camera, it's
photographic (or digital) art, not photography. But that's my narrow
deifinition. I have some "digital art" hanging in the walls of my home, but
I know what it is...

It is pertinent to assert that it is _unlikely_ that the average person
could afford to have the media rescued. Heck, if you have enough money
today, you can reconstruct a crushed RP03 disc from 1977.

Affordability is the issue. I can read reel-to-reel computer tapes, too
because I have a place to store the monster. I'd be happy to rescue tapes -
at a monsterous expense to the buyer.

Seen Wired lately? Nice article on archiving entitled "Point and Shoot and
